This invention relates to an improved smokers pipe, and the primaryobject of the invention is to provide a pipe than can bethoroughlycleaned without the necessity of taking the pipe part or emptying thetobacco from the bowl.

Another object of the invention is to provide a smokers pipe that isunique in structure, comprising a few simple, durable parts that areeasily assembled and the entire pipe being inexpensive to manufacture.

With the above and other objects and advantages in View, the inventionconsists of the novel details of construction, arrangement andcombination of parts more fully hereinafter described, claimed andillustrated in the accompanying drawing in which:

Figure l is a longitudinal, sectional view of an embodiment of theinvention with the plunger in smoking position;

Figure 2 is the same, with the plunger is cleaning position;

Figure 3 is a longitudinal, sectional view of the plunger;

Figure 4 is a sectional view on the line 4-4 of Figure 3;

Figure 5 is a sectional View on the line 5-5 of Figure 1;

Figure 6 is a perspective view of the valve on the end of the plungerand Figure '7 is a sectional view on the line 'I-I of Figure 1.

Referring more in detail to the drawing, the reference numeral llldesignates a pipe bowl, having the bowl chamber I2 and a horizontalthreaded bore I4 for reception of the threaded end I6 of the tubularbody shank or stem I8 projecting therefrom at an inclined relation tothe bowl. In-

serted in the free end of the stem I8 is the removable mouth piece orbit 20 having a reduced portion 22 and an internally threaded bore 24for reception of the threaded end 28 of the plungerl The punger 28 isprovided at one end with the elongated slot 30 and at the opposite endis threaded at 32 to receive the internally threaded valve 34, havingthe curved seat 36 which will coact with the selective port 38 in thebottom of the bowl chamber I2, and the port 40 in opposed relation tothe port 38. Therefore, port 38 communicates with the chamber I2 andport 40 communicates with the atmosphere.

In assembling the pipe, a nut 42 on the plunger 28 locks the bit andplunger in fixed relation to each other so that by turning the bit, theseat 36 in the valve will coact with either one of the ports as inFigure 1 for smoking of the pipe, and in Figure 2 for the cleaningthereof. A cork gasket 44 is positioned in the stem I8 for fixedengagement with the reduced portion 22 of the bit for an airproof joint,yet will permit rotation of the bit as desired.

2 The pipe can thus be cleaned at short intervals by rotating the stemto place the valve in Communication with the atmosphere, and with-` outremoving the tobacco the smoker can blow into the bit and the moisturewill pass out the Aport 43,after which the bit can be again rotated forsmoking.

It will be impossible to draw moisture into the mouth, since the onlycommunication the bit has with the stem is the slot 30 in the plunger 28and the stem forms a reservoir which will trap the moisture and preventthe moisture from entering the smokers mouth. By pulling the bit and itscomponent parts out of the stem, the stem can be cleaned, since thevalve which has a close fit with the stem will scrape the stem clean asit it is withdrawn.

There has thus been provided, a pipe that will accomplish the object ofthe invention and it is believed that the construction and operation ofthe invention will be apparent to those skilled in the art, and it is toIbe understood that changes in the minor details of construction may beresorted to, providing they fall within the spirit of the invention andthe scope of the appended claim.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

A smokers pipe comprising a bowl having a tobacco chamber, a threadedbore and two alined ports therein, one of the ports communicating withthe bore and chamber and the other port communicating with the bore andopen to the atmosphere, a removable tubular stern threadably connectedat one end to the bore in the bowl and a mouth piece removably connectedto the opposite end of the stem, a plunger threadably connected to themouth piece and extending into the stem, said plunger having anelongated slot at its connection to said mouth piece, and a valvethreadably connected to the opposite end of the plunger, said valveincluding a curved seat whereby upon rotation of said mouth piece saidseat will be positioned opposite to either of the ports for the smokingor cleaning of the pipe,
